Poor service at Nedbank Motherwell branch

I am not happy with Nedbank Motherwell branch service ,it is month end and there are 3 tellers which are also slow and talking instead of working , they take 40 min to assist 1 person because they are talking to each other .When I have to come to this branch I get frustrated because I know I have to stay the entire day people are tired of this branch Needs to do something
